In covering ungrooved Cuban heels 1t 1s generally the practice to coverthe rear portion and the sides of the heel with one piece of coveringmaterial and to turn the forward marginal portions of the covering overthe breast corners of the heel and adhesive-1y to secure them to thebreast of the heel in such" a manner that one of the marginal portionswill overlap .the other, the seam formed be: tween the overlappingmarginal portions oi the covering being located approximately at thecentral portion of the'breast. There are certain disadvantages in heelscovered as described above, one being that the seams formed by theoverlapped portions of the coverings are likely to breakopen and thusdetract from the appearance of the shoe.

In order to overcome this disadvantage and to provide durable heelswhich are neat in appearance, certain improved features of covered heelconstruction :have' been disclosed and claimed in United States LettersPatent Nos. 1,7 04,204 and 1,718,177 issued March 5,

1929, and June 18,1929, respectively, on ap- 7 1,718,177, a heel isprovidedhaving a'groove in the centre of its breast and extendinggenerally height-wise of the heel, into which groove a. one-piececovering stretched over and conforming to the rear, sides and breastsurfaces of the heel has its marginalportions inserted and securedtherein Asset forth in the above-mentioned Letters Patent No.

the breast surface between the ribs being I marginal portions of theside'covering should be trimmed accurately in order to have the sidecovering fit properly in the grooves. It is quite difi'icult accuratelyto trim the' mar-- ginal port-ions of these coverings by hand and suchprocess is slow and requires a high de? gree of. skill on the part ofthe operator. 7

An object of the present invention is to provide a reliable machine forexpeditiously trimming the coverings of heels for reception in groovesin the breasts of the heels.

With the above object in view and in accordance with a feature of theinvention, the illustrated machine is provided with instrumentalitiesillustrated as a disk cutter to trim a marginal portion of'a coveringattached to a heel for preparing that portion for insertion in a groovein the breast of the heel and means thereto, which gage is constructedand arranged to engage within the groove to position the heel"relatively to the table. In order to position the marginal portion ofthe covering upon the table and to retain the 'tion of the covering andhaving a gage fixed same so positioned as the trimming operationprogresses, thettable carries a holddown'device arrangedformovementtoward and away from the table" to press the marglnal portion of thecovering against the table and against the breast of the heel. Inaccordance with a i further feature of the invention, the illus tratedmachine is provided with a guideway constructed and arranged fordeterminingthe path of movement ofthe heel positioned upon the tablepast the rotary cutter -to trim the marginal portion'of the coveringattached totheheel. r

. With the above and other objects in view the invention will now bedescribed in connection with the accompanying drawings and pointed outin the claims.

Fig. 2 is a perspective view ottlie machine and the heel shown in Fig.1;

Fig. 3 is an enlarged perspective view of the machine fitted for trmming the marginal portions of the side covering of heels for insertionin curved grooves in the breasts ot' the heels and adjacentto the breastcorners of the l1eels,portions of the machine being broken away moreclearly'to illustrate the heel positioning and trimminginstrumentalitiesyand Fig. dis a perspective view of a portion of themachine, part of which has been broken away to show a section takenalong the line IV -IV of Fig. 3 and illustrating a heel in the processofhaving the marginal portion of its side covering trimmed in the machinefor preparing the same for insertion in a groove following abreastcorner of the heel.

The illustratedh'eel-cover trimming machine includes a disk or rotarycutter 10 for trimming a covering'l2 to prepare it for insertion ineither one of two forms in grooves 14 (Figs. 1 and 2), 16 (Fig. 4) inthe breast of a heel 18, gages 20 (Figs. 1 and 2) and 22 (Figs. 3and 4)constructed and arranged to engage within the grooves .14 and 16respectively to position the heel 18relatively to the' disk cutter 10, atable 26. which carries either one of the gages 20, 22, for supportingthemarginalportion 24 of the covering and a holddown device 28 toposition the marginal portion 24 of the covering upon the table 26 forpresenting the same to thecutter 10, the table 26 together with eitherof the gages 20 and 22 and the holddown device 28 being mountedformovement pastthe cutter 10 for carrying out the trimming operation.

The above-referred to instrumentalities for facilitating the positioningof the heel 18 and the marginal portion 24. of the heel coveringrelatively to the cutter 10 and for trimming the covering aresupported upon. a. standard 30 including a bracket 32 secured theretobyscrews 34.- (Figs. land 4), which bracket carries a plate 36 :clampedto its forward end (Fig; 2) 'For conveniently raising or lowering theheel positioning instrumentalities the plate 36Iis mounted foradjustment in a vertical direction relatively tothe standard 30, theplate36 being heldin the desired verticalposition by a bolt38 which isscrewed into the bracket 32 and-passes through a slot l0 in the plate36.In orderto' prevent lateral shifting between the bracket 32 and theplate 36 as the above-described vertical adjustment is effected, thebracket 32 is provided with a vertically extending recess 4-2 forreceiving a tongue portion -14 ofthe plate 36. The upper forward portionof the plate 36 includes a horizontally disposed dove-tail tenon i6which is constructed and arranged to mate with a dove-tail mortiseportion 18 (Fig. 4:) in a depending flared portion of the table,

thus providing a guidcway for slidingl v supporting thetable as it movedpast the retary cutter 10 to carry out the trimming operation; whichwill later be described.

The cutter 10 is mounted upon the end of a shaft 52 by a screw 54, theshaft being supported for rotation in any conventional manner in theupper portion of the standard 30. a

The table 26 upon which the marginal portion 24: of the heel covering issupported at opposite sides of the cutter 10 as the trimming operationprogresses, comprises a hori- ZOlliiZLl'POltlOIl 56 and the dependingflared portion 50 by which it is supported and guided as abovedescribed. In order to sure a snug sliding fit between the mortiseportion 4180f the table 26 and tenon portion 46 of the plate 36 thetable is provided with a gib58 (Fig. 4) which may be convenientlyadjusted by the screws 60. The central portion of the tablehas a recess62 extending therethrough for conveniently disposing of the surplustrimmings. The portion of the table upon which the marginal portion 24:of the covering is presented to the cutter 10 preferably consists of acomposite pad 6% of a relatively soft material which is held in positionand is easily replaceable upon the horizontal portion 56 of the tableby'the screws 66. 'The composite material fi l may be integral with thetable and for purposes of illustration will be considered as part ofthetable. 3 i a i In order to position the heel 18 relatively tothe'table 26 and the cutter 10, the machine is provided withthe gages20, 22 secured to the table 26 by screws 68 (Fig. 1), 66 (Fig. 4"),respectively, thefitypeof used dependingupon whether it is desired totrim the marginal portion 24: of the covering for insertion intothegroove 14 which is positioned in the center of the breast of the heelandlies in asingle plane or for insertion into the curvedgrooves 16 inthe breast of the heel andsubstantially parallel to the breast cornersoftheheel. Itwill bcnoted that the gagei20is securedto the table near thelower surface .72 thereof and that the gage is clampedbetween thecomposite pad and the horiozntalportion' 56 of the table. Since thecenter groove 14e'lies in a single plane the gage 20'Wl11l1 engageswithin that groove maybe of considerablelength so thatit'erjtendsbeyondthe attaching face and the top liftsattaching rface of the heel as shownin (Fig. 2- i he length. ofthe'flat heel ngag p r ion 76 (E gever thegage 2.2 however quite short .inorder to provideor its i vsi-tioneiliectively the heel 18 relatively to the table 26.

To position'the marginal portion 24 of the covering upon the table 26and to retain (F gsthe same so positioned thereon as the table is movedpast the cutter 10, the machine is provided with the holddown device 28movable toward and away from the table 26 upon rod 7 8 which extendsthrough a portion of the table 26 and is secured against movementrelatively to the table in the direction of its axis. The holddowndevice 28which is thus arranged for movement with the table includes theelongated bar 79 L-sh,aped in cross-section attached to an arm 80 whichis secured at 82 to the rod .78 for moving the bar 79 toward and awayfrom the table 26 as above stated. Thebar 7 9 is constructed andarranged to press the marginal portion 24; of the covering .against thetable 26 and against thefibreast of the heel (Figs. 1 and a) whentheheel18 ha'sibeen positioned upon either of the gages 20, 22.

It will be notedthat in trimming the marginal portions- 2% ofthecoverings for the two types vof groovedheelsabove described that the bar79 engages .the'coverings against different port-ions otthe breasts ofthe heels. In center groove work, such as shown in 1 and '2, the flange8 1i of the bar -7 9 engages 1) to posit-ion the heel cfoveringrelativelyto the table 26, while in the curved groove work, suchas shownin Figs. 3 and l, the flange 88 and 4) of the bar 79 engages thecovering upon" the breast of the heel near one of the breastcorners ofthe heel while positioning the marginal portion of the heel.eoveringrelatively to the table 26. In order conveniently to operatethe holddown 28 and tomove the table- 26 pastthe cutter 10, the rod 7 8is provided witha curved end portion .90 (Figs- 1 and 2) upon the endportion of which is mounted a handle 92. The sliding movementof thetable 26 upon the'tenonportion 46 of the plate. 36 is limited by a screw93 (Fig.1) and a pin 95 fixed to the plate To protect the operatorduring the heel trimming operation," the machine is provided with aguard 94 pivotally mounted upon an "arm96 which has a slot 98 (Fig. 2)arranged to receive a bolt 100 threaded into the top of the standardSO'for adjustably securing the guard 94: in the desired-positionrelatively to the cutter 10. The guard 94 is normally held -in'it'srear' position (Figs. 1 and 2) by a' spring .102 the end portionsofwhich are secured-to the studs 104,106of the arm and the guard,respectively. r 1
